Fox news takes flak because it doesn't actually give a balanced look at the issues it reviews. Worse, it does no fact checking whatsoever. A popular example of this was the way that Fox News repeatedly (even to this day) would push a relationship between Iraq and 9/11, even though no such relationship exists. Fox doesn't present news, it presents unresearched and often irrational opinions that clearly favor a rather ignorant political viewpoint.
Case in point, conservative isn't a political party, its a philosophy. You can be an "independant" and still be conservative. That's not really a mistake anyone watching The Daily Show is likely to make.
